With Bluetooth support service, you can sync Android data to iPhone, receive calls, etc, while this feature doesn’t always work seamlessly, as it is not always successful to pair two devices via this connection. The issues that are causing the Bluetooth connection to fail can be related to both hardware and software which makes it somewhat difficult to detect the root of the problem.

What Causes Bluetooth Connection Problems

Establishing the Bluetooth connection is only possible if this feature is working properly on both devices. The Bluetooth technology is backward compatible, which means that the devices you are trying to pair don’t necessarily have to be using the same version of Bluetooth.

Consequently, pairing a device that is using Bluetooth 5.0 with a device that is equipped with a now obsolete Bluetooth 2.1 shouldn’t be a problem. However, pairing a webcam and a mouse isn’t possible even if both devices Bluetooth capable. Because cameras don’t offer support for Human Interface Device Profile.

Besides the incompatibility of devices, Bluetooth not connecting can be caused by the current settings on your phone or the clogged RAM. Resolving these issues isn’t complicated and in most cases, it takes just a few moments of your time.

How to Fix Bluetooth Issues on an Android Phone

A Bluetooth connection issue can be caused by a wide range of software and hardware malfunctions. Instead of trying to detect the reason why the connection failed you can attempt to resolve the problem by using some of the most common solutions.

Here’s what you can do to fix Bluetooth issues on an Android phone.

Unpair Connected Devices

Your phone remembers the devices you paired it with, which sometimes can be the reason why it fails to connect to a new gadget. In order to avoid this issue, you just have to remove the devices you are no longer using and then try to establish a connection with a new one.

Step 1: Go to the Settings app, open the Bluetooth menu, and tap on the Connected Devices option. Make sure that Bluetooth is enabled and browse through the list of gadgets you already paired with your phone.

Step 2: Tap on the Remove, Delete or Forget option next to each device you no longer want to use with your Smartphone and once you’re done proceed to establish a connection with a new device.

Reboot your Phone

Restarting your Android phone will cancel all the settings that may have disrupted a Bluetooth connection temporarily.

After your phone reboots, you should open the Settings app and enable the Bluetooth feature if it was deactivated. Then try to connect the gadget to your phone via Bluetooth to make sure that the feature is working properly.

Clear the Data and Cache

Like all other applications on your phone, Bluetooth accumulates data and cache over time. This data can sometimes impact the device’s ability to connect to other gadgets. So, it is important to clear the Bluetooth cache and data regularly.

Step 1: Open the Settings app, and navigate to the Application Manager menu. Browse through the apps and services on your phone until you find Bluetooth. Tap on it and then choose the Storage feature.

Step 2: Tap on the Clear Data and Clear Cache buttons to remove them from your phone. Restart the Smartphone and try to establish a Bluetooth connection with a preferred device.

Switch on the Discoverable Mode

If your device is not visible to others, you won’t be able to connect your phone to your car’s infotainment system or other gadgets that support Bluetooth. This is a simple task that can be completed in just a few taps.

Step 1: Choose the Bluetooth option from the Settings menu, and make sure that the feature is enabled.

Step 2: You will be able to see several settings after you switch on the Bluetooth option, so you just have to find the setting that enables the device to be discovered by other Bluetooth gadgets and then try to pair your phone with another device.

Keep the Pairing Devices Closely and Stay Away from a WiFi Router

Android phones don’t have a large Bluetooth range, so keeping them close to each other is vital for establishing the connection between them. The devices you are trying to pair through Bluetooth shouldn’t be more than five feet apart.

Besides, a WiFi router may interfere with the Bluetooth connection between two devices, so you should make sure you are not in the immediate proximity of a router.

The Bottom Line

In most cases, toggling this option off and on or restarting your Smartphone should be enough to resolve any Bluetooth connection issues you may be experiencing. Also, it is important to check if the device you’re trying to connect to your phone is working properly. If the basic tips didn’t work for you, try the above methods one by one.
